Wow this is a really great one and has loads of potential! I love how there is no purposefully evil person, Estrelle is gradually getting better through several chapters instead of one panel, there were actual reasons for why she was left like that and even though it doesn't seem to be the king's fault he is trying so hard to make up for it and provide and protect her. Also these sibs are actually really sweet and nice??
Only the maids are sus for now but then again they probably don't have the capacity, knowledge or patience on how to look after a child like Estrelle. But they're still trying even though they don't like it and don't know how to act and that's leagues better than most characters in other series (I'm looking at you Sincerely A Duke's Maid).
Thank you for the chapters!!
